Y Post 358 Fence Supplier
The Y post 358 fence system consists of heavy-duty 358 anti-climb mesh panels, structural Y-shaped posts, and integrated top extension arms. It is a common perimeter fence system used in high-security projects such as prisons, airports, data centers, and power facilities.
Compared to traditional square or round post systems, Y-shaped posts are structurally designed with integrated mounting points for top brackets, allowing for the direct installation of razor wire, barbed wire, or electronic fence systems without the need for on-site welding of additional brackets. This streamlines the installation process and also reduces the retrofitting cost when adding top-of-post security features later on.
In addition, the 358 anti-climb mesh features a 76.2 mm × 12.7 mm mesh size. This narrow mesh design effectively prevents people from climbing while maintaining good visual transparency. When combined with the Y-shaped post structure, it creates a more comprehensive top-of-fence protection zone, enhancing the overall perimeter security level.
We offer customization options for various Y-arm configurations, including 30°, 45°, and Double Y Arm, and can adjust post specifications, wall thickness, fence height, mesh size, and surface finishes. Simply provide us with your project drawings, on-site measurements, or technical specifications, and we will recommend the most suitable fence configuration for your needs. We also provide concertina razor wire, barbed wire, security gates, and installation accessories to facilitate procurement and on-site installation for your project.
Our Y Post 358 Fence Systems
Offers excellent value for money and high versatility. We can customize the height, post wall thickness, and surface finish based on your project drawings.
Designed specifically for high-risk, high-security areas, this system adds razor wire to the top of standard 358 fencing. Widely used in prisons, airports, military bases and other high-security facilities.
Integrates high-quality barbed wire at the top as a cost-effective alternative to razor wire. It is a choice that balances cost and security.
Allows for the simultaneous installation of multiple layers of razor wire or barbed wire, creating a wider protective zone at the 358 fence top and effectively making it more difficult to scale.
The 30-degree outward-tilting Y-shaped support arm eliminates the leverage point for anyone attempting to climb over it and maintains a clean, modern appearance.
Further expands the protective coverage at the 358 fence top. Ideal for prison upgrades and high-security critical facilities.
Stronger Y Post Security Structure
We adopt an advanced integrated bending forming process, allowing the Y-shaped double suspension arms to come with standardized anchor bases directly. On the construction site, you do not need to perform cumbersome welding or install additional rear supports. Just assemble it directly. This modular setup reduces field installation time by up to 40% and drastically lowers labor costs.
Our Y-arm post structure has been specially strengthened, and it can withstand a total load of over 80 kilograms. You can use it to mount single- or double-layer BTO-22 concertina razor wire; it will not bend or sag, even when used to support heavy-duty protective netting over long periods. Furthermore, the reinforced post profile boosts lateral wind-load resistance by over 35%. Even when facing severe winds, long-term outdoor exposure, or frequent external force impacts, it can provide you with extremely high structural stability.

Both Y Post and C Post are common column systems used in 358 security mesh fences, but they are suitable for different applications.
Y Post 358 Fence: Built with integrated top extension arms to support concertina razor wire, barbed wire, or electronic fencing. Specially designed for high-security projects such as prisons, airports, data centers, and power facilities, it can completely block the possibility of climbing from the top by providing physical security.
C Post 358 Fence: Features a compact C-shaped profile with a sleek, minimalist footprint. If additional top anti-climbing facilities are needed later, it needs to install additional support arms.
When your project requires a complete high-security perimeter protection system and plans to install top protection facilities, Y Post is usually a more suitable choice. But when the project mainly focuses on cost control and does not require a top security configuration, C Post will be a more economical choice for you.
It should be designed comprehensively, considering the fence height, soil conditions, wind load, and the weight of the top protective facilities.
Generally, the Y-shaped posts are installed using pre-buried concrete. We can adjust the post size and depth according to the project requirements.
If the installation ground has already been hardened (such as a cement pavement), we supply customized flange base plates for direct anchoring with expansion bolts.
If your project is located in a strong wind area, or the top is permanently equipped with heavy razor wire or electronic fences, we recommend appropriately deepening and increasing the concrete foundation to provide strong stability.
You should select the surface treatment method based on the local environment, the required service life, and the budget.
Hot-Dipped Galvanized: Best for standard inland environments. It offers cost-effective basic protection for projects in industrial parks, warehousing, and logistics.
Hot-Dipped Galvanized + Powder Coated: Recommended for coastal areas, high humidity environments, industrial pollution areas, and those corrosive conditions. The galvanized layer provides basic corrosion protection, and the powder coating further isolates moisture and air for Y post 358 fence, improving long-term weather resistance. It also supports RAL color customization.
Hot-Dipped Galvanized + PVC Dip Coating: Features a thicker protective layer with exceptional impact and abrasion resistance. It is very suitable for public areas such as residential communities, schools, and parks that frequently face mechanical abrasion.
We use special anti-tamper connectors and anti-theft bolts. Through the mounting plate or slot, the high-density 358 mesh is tightly locked onto the post. This ensures structural stability and prevents violent disassembly, and is also convenient for local maintenance and replacement in the future.
In addition, the Y-shaped support arm adopts an integrated reserved hole design without welding at the post’s top. You can directly mount the razor wire, eliminating the cumbersome secondary welding process on site, and significantly saving your construction labor and time.
If you have project CAD drawings or specified installation standards, we can also provide corresponding connection methods and installation accessories as per your requirements.
The installation height needs to be determined based on the project’s safety level, perimeter protection requirements, local wind load, and top protection configuration. There is no fixed maximum height.
In standard engineering practice, the common height for a Y-post 358 fence is from 2.0m to 3.0m, meeting most protection needs.
If you want to increase the fence height, the wind load borne by the posts and the top accessories’ weight will also increase. At this time, we will upgrade the posts’ wall thickness and section, densify the post spacing, or deepen the foundation. These measures can ensure that the entire 358 fence perimeter system does not undergo structural deformation due to the excessive height.
To minimize coating scratches and post-deformation during international transportation, we usually use steel pallets or metal pallets for packaging and secure them with protective films, corner guards, and straps.
At the same time, the 358 mesh, Y posts, and hardware accessories are packaged separately for classification. This allows you to conduct on-site counting, distribution, and installation more quickly and efficiently. This also significantly increases the loading rate of containers (such as 40HQ), effectively saving your logistics and maritime transportation costs.
